When air is blown across the top of an openwater bottle, air molecules in the bottle vibrate
at a particular frequency and sound is produced.
This phenomenon is called
(1) diffraction (3) resonance
(2) refraction (4) the Doppler effect

Answers

Answer 1
Answer: When air is blown across the top of an open water bottle, air molecules in the bottle vibrate at a particular frequency and sound is produced in a process called "refraction". 
Answer 2
Answer:

Answer:

resonance

Explanation:

Resonance is when the frequency matches another objects natural frequency causing it to vibrate.

Color corresponds to the ______________ of light waves..A. Wave Speed

B. Cycles

C. Wavelength

Answers

The correct answer is

C.wavelength



In fact, the colour of visible light depends on the wavelength of the wave. The visible light spectrum goes approximately from wavelength of 380 nm (corresponding to violet light) to 750 nm (corresponding to red light), and the different colours in between correspond to different wavelengths. For instance, blue light has wavelength of 450-500 nm, while yellow light has wavelength of 570-590 nm.
Color corresponds to the wavelength of light waves.
The shortest light waves are "violet", the longest light waves are "red".

What is the acceleration of a body revolving in a circle at uniform speed? The acceleration is zero. The acceleration is directed tangentially. The acceleration is directed toward the center. The acceleration is directed away from the center.

Answers

A body revolving in circle generally has tangential acceleration if the speed is changing. Since the speed is uniform here, the tangential acceleration is zero.

centripetal acceleration is directed towards the center and is given as

a = v²/r                    where a = centripetal acceleration , v = speed , r = radius

Since both speed and radius are constant here, the centripetal acceleration is constant and is always directed towards the center.

hence the correct choice is

The acceleration is directed toward the center.

A 15g bullet travelling at 100m/s strikes and is absorbed by a 75kg object. Find the speed at which the final object moves.

Answers

The final object will move with a speed of 1.9 x 10⁻² m/s.

What is law of conservation of momentum ?

According to the law of conservation of momentum, when two objects meet in a closed system, the sum of their momentums before and after the collision is constant.

Here,

Initial velocity of the bullet, u = 100 m/s

Mass of the bullet, m = 15 g = 0.015 kg

Mass of the object, M = 75 kg

Total momentum before collision, P₁ = mu + (M x 0)

P₁ = 0.015 x 100

P₁ = 1.5 Kgm/s

Total momentum after collision, P₂ = (m + M)v

P₂ = (0.015 + 75)v

P₂ = 75.015 v

According to law of conservation of momentum,

P₁ = P₂

1.5 = 75.015 v

Therefore, the speed with which the final object moves,

v = 1.5/75.015

v = 1.9 x 10⁻² m/s

Hence,

The final object will move with a speed of 1.9 x 10⁻² m/s.

Which of the following areas would most likely have the deepest layer of topsoil?

Answers

Desert

The loss of top soil in very dry areas of the world is known as desertification. Desertification is the phenomenon in which land degradation of a very dry region increases and the water bodies typically dries up. This also results in not only loss of vegetation but also animal life. This phenomenon can be caused not only due to climate changes, but also due to human activities.

What is the kinetic energy of a 1.40 kg discus with a speed of 22.5 m/s?

Answers

Kinetic energy = (1/2) (mass) (speed)²

                         = (1/2) (1.4 kg) (22.5 m/s)²

                         =    (0.7 kg)  (506.25 m²/s² )

                         =          354.375  kg-m²/s²  =  354.375 joules .

This is just the kinetic energy associated with a 1.4-kg glob of
mass sailing through space at 22.5 m/s.  In the case of a frisbee,
it's also spinning, and there's some additional kinetic energy stored
in the spin.
